2 Commencement
This instrument commences on 29 January 2018.
3 Authority
This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986.
4 Revocation
The Statement of Principles concerning migraine No. 57 of 2009, made under subsection 196B(3) of the VEA is revoked.
5 Application
This instrument applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies.
6 Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about migraine and death from migraine.
Meaning of migraine
(2) For the purposes of this Statement of Principles, migraine:
(a) means migraine without aura, migraine with aura (which includes basilar migraine, sporadic hemiplegic migraine and retinal migraine), chronic migraine and vestibular migraine; and
(b) excludes familial hemiplegic migraine, abdominal migraine, migrainous infarction, amaurosis fugax, cluster headache, tension-type headache, headache attributable to structural abnormalities or inflammatory disorders of the head and neck, and headache attributable to systemic disease.
Note: chronic migraine, migraine with aura, migraine without aura and vestibular migraine are defined in the Schedule 1 – Dictionary
(3) While migraine attracts ICD‑10‑AM code G43, in applying this Statement of Principles the meaning of migraine is that given in subsection (2).
(4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from migraine
(5) For the purposes of this Statement of Principles, migraine, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's migraine.
Note: terminal event is defined in the Schedule 1 – Dictionary.
8 Basis for determining the factors
On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that migraine and death from migraine can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.
9 Factors that must exist
At least one of the following factors must exist before it can be said that, on the balance of probabilities, migraine or death from migraine is connected with the circumstances of a person's relevant service:
(1) undergoing treatment with a nitric oxide donor, at the time of the clinical onset of migraine;
Note: nitric oxide donor is defined in the Schedule 1 - Dictionary.
(2) undergoing treatment with a nitric oxide donor, at the time of the clinical worsening of migraine;
Note: clinical worsening of migraine and nitric oxide donor are defined in the Schedule 1 - Dictionary.
(3) being obese for at least the five years before the clinical worsening of migraine;
Note: being obese and clinical worsening of migraine are defined in the Schedule 1 - Dictionary.
(4) inability to obtain appropriate clinical management for migraine.
10 Relationship to service
(1) The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.
(2) The factors set out in subsections 9(2) to 9(4) apply only to material contribution to, or aggravation of, migraine where the person's migraine was suffered or contracted before or during (but did not arise out of) the person's relevant service.
11 Factors referring to an injury or disease covered by another Statement of Principles
In this Statement of Principles:
(1) if a factor referred to in section 9 applies in relation to a person; and
(2) that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(3) of the VEA;
then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
